Assembly comprising at least two components that are fixed together

Abstract

The invention relates to an assembly for a motor vehicle, comprising at least a first component (T, FA, FB) and a second component (FS, G), for example a carrier and a guide rail of a window lifter which are fixed together by means of at least one fastening element, in this case by a plurality of rivets (N1-N4). A fastening element (N1-N4) engages in two openings (72, 82, 92; 62; 62'), of which one opening respectively is formed in a receiving portion (7.1-7.4; 8.3, 8.3*, 8.4; 9.3, 9.4) of the first component (T; FA; FB) and one on a protrusion (6.1-6.4; 6.3', 6.4') of the second component (FS; G), wherein a protrusion (6.1-6.4; 6.3', 6.4') respectively protrudes in an associated receiving portion (7.1-7.4; 8.3, 8.3*, 8.4; 9.3, 9.4) and a flexible or elastic edge section (70, 80, 90) of a receiving portion (7.1, 7.3, 7.4; 8.3, 8.3*, 8.4, 9.3, 9.4) can be shifted in the direction of the associated protrusion (6.1-6.4; 6.3', 6.4'). The at least one edge section (70, 80, 90) that can be shifted in a flexible manner is designed and provided for compensating manufacturing tolerances, such that the two components (T, FS; FA, G; FB, G) automatically align to one another in the area of the flexible edge section (70, 80, 90) during the fastening process and can form a solid connection as intended, wherein the protruding section (6.1-6.4; 6.3', 6.4') is locked in the receiving portion by the edge section (70, 80, 90) which is shifted and pushed against the protruding section (6.1-6.4; 6.3', 6.4').

Description

technical field [0001] The invention relates to an assembly for a motor vehicle having at least one first and a second component according to the preamble of claim 1 and to a device for fastening two components of a motor vehicle assembly to one another. method. Background technique [0002] Fastening elements (for example screws or rivets) are often used to connect the components of a motor vehicle assembly, which clamp the two components together and in which case at least one of the two components passes through (through) the opening. Such fastening elements thus respectively engage into openings on the two components in order to fix the two components in relative position to each other. For example, the first opening on the first component is formed as a through opening and the second opening on the second component is formed as a through opening or a blind hole opening. Here too, the opening on a component can first be formed by providing fastening elements, as is the...

Problems solved by technology

[0003] When fixing two components in this way, the problem often arises in practice that undesired stresses and deformations are introduced at least locally into at least one of the two components via the fixing element

[0005] The device described in DE 198 47 268 A1 with a set-back connection section on one of the two components to be connected to each other here also overcomes the clamping to a certain extent, which is achieved by Observation: When a plurality of identical fastening locations with two openings in each case are provided on two components,—depending on manufacturing tolerances—the openings on the two components that are to be formed superimposed on each other are not aligned exactly with one another.
